TECHNICAL FIELD The present invention relates to, for example, a flexible board connector which is wire-connected on a control board of an apparatus. More particularly, the present invention relates to a flexible board connector that enables miniaturization by improving the connection structure.

(Prior art)

In general, this type of flexible board connector is provided with an attachment hole 193 for inserting and attaching a conductive tip of the flexible board (FPC) 192 to the front side of the housing 191. A plurality of contacts 194 are arranged in parallel with the conductive tip of the flexible substrate in contact with the conductive tip of the flexible substrate, and the tip of the flexible substrate 192 is placed inside the attachment port 193. The conductive front end portion of the flexible substrate 192 is pressed against the contact portion 194a of the contact 194 by sliding the slider 195 from the outside to press into the attachment hole 193 while facing the cavity. The connection is fixed.

In addition, in the parallel arrangement | positioning of the contact 194 assembled in the housing 191, each contact 194 is press-fitted and attached to each contact indentation groove 191a formed in parallel in the rear part side of the housing 191. .

As shown in FIG. 20, when the contact 202 is press-fitted and attached in the front-rear direction of the housing 201, the contact 202 is press-fitted in the front-rear direction with respect to one housing 201. And the outer end portion 202a of the contact 202 can be taken out from the front and rear directions of the housing 201 on the substrate 203, so that there is a lot of wiring connectivity on the substrate 203. In addition, it is possible to promote the miniaturization of the connector.

By the way, when the miniaturization of the flexible board connector is promoted, as shown in FIGS. 21 and 22, the thickness in the parallel direction of the contacts 212 disposed in parallel in the left and right directions of the housing 211 is as thin as possible. In addition, the parallel pitch of the contacts 212 is narrowed to the limit.

For this reason, when a contact becomes thin, the elasticity of the contact itself will be lost, and stable contact force with a flexible substrate will not be ensured. Further, if the contact is made narrower in pitch, the inter-contact resin layer 213 becomes thinner, and at the time of resin molding of the housing, the mold part becomes too thin and brittle, and since the inter-contact resin layer 213 is thin, resin filling Shortage occurs and it is easy to cause molding defect.

In addition, as shown in FIG. 23, the contacts 232 and 233 are press-fitted and fixed in the front and rear directions of the housing 231, and the contact portions of these contacts 232 and 233 are also brought into the bottom contact type to achieve miniaturization. One is known (for example, refer patent document 1 and patent document 2). In the figure, reference numeral 234 denotes a slider 234, and reference numeral 235 denotes a flexible substrate 235.

However, in order to secure the insulation distance of each contact in the front and rear, left and right, to avoid the thinning of the contact, and to secure the spring length in the long contact direction, to make the contact itself stable contact response performance, the contact length becomes long and it becomes difficult to miniaturize. .

As illustrated in FIG. 24, the front contact 242 and the back contact 243 are arranged to face each other in the front-rear direction of the housing 241, and the front contact 242 is the bottom contact 242a. It is also known to have an up-and-down contact type in which (243) is composed of an upper contact point 243a (see, for example, Patent Documents 3 and 4).

However, in this case, in order to correspond to an up-and-down contact, the conductor part of the flexible board edge part must be provided in both front and back, and a flexible board becomes expensive. Moreover, the contact part is divided up and down, and it becomes a complicated structure to apply the contact structure of ZIF type which presses and contacts the conductor part of the flexible board edge part with the contact point of upper and lower sides using pressure members, such as a slider and a lever. In addition, although it is necessary to secure the insulation distance between the front, rear, left, and right of the contacts disposed in parallel in the housing, there is a limit in miniaturization in the present state.

[Patent Document 1] Japanese Patent Laid-Open No. 9-97665.

[Patent Document 2] Japanese Patent Application Laid-Open No. 11-54220.

[Patent Document 3] Japanese Patent Laid-Open No. 9-171858.

[Patent Document 4] Japanese Patent Application Laid-Open No. 11-339901.

Therefore, the present invention can arrange and arrange a plurality of contacts assembled in the housing in a zigzag form even in the planar direction and the height direction, thereby ensuring an appropriate insulation distance between the contacts, and further facilitating manufacturing and miniaturization. It is an object of the present invention to provide a connector for a flexible board which is made possible.

(Means to solve the problem)

The present invention provides an insulating housing in which a mounting hole for attaching a flexible substrate is opened on the front surface side, and a plurality of contacts arranged in parallel to the left and right in contact with the conductive tip of the flexible substrate in contact with the conductive tip of the flexible substrate in the left and right directions are provided. The location of the contact parallel to the left and right directions is divided into two rows of the heat transfer side and the rear heat side of the housing, and the contacts in the front and rear two rows are arranged in a zigzag shape in the plane direction, and the upper side also in the height direction. It divides into two rows with the lower side, and arrange | positions each contact of the upper and lower two rows in a zigzag form also in an up-down direction, protrudes the outer end part of a heat transfer side contact to the front side of a housing, and the outer end part of a rear row contact is a housing | casing. It is a connector for flexible boards which protruded to the back side.

The flexible substrate is a strip-shaped electrical wiring in which a plurality of wirings are integrated and integrated in parallel with an insulating member having flexibility.

The attachment hole can be configured by opening an elongated opening to allow the insertion of a strip-shaped flexible substrate to the front surface of the housing.

The contact is made of a conductive member, the inner end of which is attached at a position corresponding to the flexible substrate contact in the housing, and the outer end of which is electrically connected and fixed on a substrate outside the housing.                         

The housing can be assembled by dispersing a plurality of contacts in a zigzag form and allowing the assembly thereof, and molding the molded resin with a synthetic resin material suitable for insulation.

According to the present invention, since the front and rear two rows of contacts are distributed in a zigzag shape not only in the plane direction but also in the height direction in the left and right directions of the housing, the contacts are three-dimensional zigzag arrangement in the housing, so that the contacts are not only in the front, rear, left and right directions, but also in the vertical direction. The distance between the contacts can be lengthened.

For this reason, even if the flexible board | substrate connector is miniaturized, it can arrange | position at the space | interval which secured the appropriate insulation distance between contacts. In addition, a thin layer of the resin layer between the contacts can be avoided and a thickness suitable for manufacturing the housing can be ensured. For this reason, the metal mold | die parts are also eliminated from a thin part, a durable mold which is hard to be damaged can be obtained, manufacture becomes easy, and further miniaturization of a housing can be promoted. In addition, the thinning of the contact can also be avoided, the contact can be terminated without losing the elasticity of the contact itself, the contact pressure with the flexible substrate can be ensured with a stable elastic contact force, and the contact reliability with the flexible substrate is improved.

In addition, since the insulation distance can be lengthened not only in the front, rear, left, and right directions, but also in the vertical direction between the contacts, shortage of resin filling between the contacts can be avoided, whereby a stable molded article can be obtained. In addition, since the front and rear two rows of contacts are arranged in a zigzag shape in both the planar direction and the height direction and do not face each other in the front and rear direction, the spring length in the contact length direction extending in the front and rear direction of the housing can be lengthened. For this reason, each contact can be made to have stable contact performance.

According to another invention, there is provided an insulating housing in which a mounting hole for attaching a flexible substrate is opened on the front surface side, and a plurality of contacts arranged in parallel in a horizontal direction in contact with the conductive tip of the flexible substrate in the inner side of the mounting hole are connected and fixed, and the An inward contact member is allowed to move in and out of the attachment port, pressurizes the conductive tip to the contact facing the upper side or the lower side at the time of advancing, and provides an insulating urging member which opens the pressing force at the time of retraction, and the contact parallel to the left and right directions. The installation position of is divided into two rows parallel to the heat transfer side and the rear heat side of the housing, and each contact in the front and rear two rows is arranged in a zigzag manner in the plane direction, and the outer end of the double heat transfer side contacts is projected to the front side of the housing, A connector for a flexible board, wherein the outer end of the side contact is protruded toward the housing rear side. Also the contacts arranged in a zigzag form in the plane direction in the height direction of the housing in two rows share one parallel to the upper side and the lower side, and is characterized in that one also arranged in a zigzag form for each contact the upper and lower two rows in the vertical direction.

Here, the pressing member is an insertion member for integrally pressing and fixing the flexible substrate to be inserted into and attached to the attachment hole of the housing, and can be configured as a slider that slides in the front-rear direction of the housing or a lever that rotates.

In this case, the distance between the front, rear, left, right, and up and down contacts can be increased, and the housing thin portion can be avoided and the appropriate insulation distance between the contacts can be ensured, so that the flexible board connector can be miniaturized. In addition, when the conductive tip of the flexible substrate is pressed against the contact facing the upper side or the lower side by the pressing member, the contact can be easily contacted, and the economical flexible of one side (one side) type corresponding to the upper or lower surface is in contact. The substrate can be applied.

As another embodiment of the present invention, a flexible board connector can be configured to press and fix a contact in the front-rear direction of the housing.

In this case, the outer ends of the contacts are dispersed in front and rear and taken out in order to attach the contacts in a zigzag form on the front and rear sides of one housing. For this reason, the wiring connection space on a board | substrate becomes enough, and the miniaturization of the connector for flexible boards can be promoted.

As another embodiment of the present invention, a flexible board connector can be constituted by press-fitting and attaching one contact formed in two rows of the heat transfer side and the rear heat side of the housing from the upper side of the housing.

In this case, one of the contacts can be press-fitted from the upper side of the housing, so that press-fitting suitable for attachment to the housing can be made. For example, in the case of a flat housing, the press fitting operation can be performed on the upper surface having a large area suitable for the pressing direction. In addition, since the contact is long in the front-rear direction and short in the height direction and press-fits in the short side direction, the press-in distance is shortened, resulting in stable attachment.

As another embodiment of the present invention, a flexible board connector can be constituted by press-fitting and attaching one contact formed in two rows on the heat transfer side and the rear heat side of the housing at the bottom of the housing.

In this case, since the contact can be press-fitted from the bottom of the housing, press-fitting suitable for attachment to the housing becomes possible. For example, in the case of a flat housing, the press fitting operation can be performed from the lower surface having a large area suitable for the pressing direction. In addition, the contact has a long shape in the front-rear direction, a short shape in the height direction, and presses in the short side direction, so that the press-in distance is shortened and stable attachment is achieved.

As another embodiment of the present invention, a flexible board connector can be configured in which all of the contact portions that connect and fix the contact with the conductive tip portion of the flexible substrate are set above the cavity part in the housing.

In this case, since the contact portion of the contact is arranged on the upper side, the one-sided type can be easily contacted with the opposing contact by simply pushing upward the conductive tip of the flexible substrate upward by the pressing member. Economical flexible substrate can be applied.

As another embodiment of the present invention, a flexible board connector can be configured in which all of the contact portions are connected to the conductive tip of the flexible substrate to be electrically connected, and the conductive portions are set above the cavity in the housing, and the height positions of the contact portions are arranged. have.

In this case, since the height position of the contact portion is arranged above, the pressing direction of the pressing member and the shape of the pressing member are not complicated, and the shape of the pressing member is simplified.

Embodiment of this invention is described in detail based on the following drawings.

[First Embodiment]

1 and 2 show a flexible board connector 11, which comprises a housing 12, a front contact 13, and a rear contact 14. And a slider 15.

The housing 12 used here is formed in the shape of a flat plate with a resin material suitable for insulation, and has an attachment hole 17 which has a long opening for connecting the flexible substrate 16 to the front surface of the housing 12. And a cavity portion 18 for connecting the flexible substrate to the inside communicating with the attachment port 17.

Moreover, the front press-in groove 19 for press-fitting and fixing all the contacts 13 individually is provided in the front side of the housing 12 which communicates with this attachment port 17 and the cavity part 18, the said housing. It is formed in parallel at regular intervals in the left-right direction of (12).

In addition, as shown in FIG. 3, the rear indentation groove 20 is parallel to the rear side of the housing 12 at regular intervals in the left and right directions of the housing 12 in order to individually press-fit the post contact 14. It is formed.

In this case, as shown in Fig. 4, the positions where the voltage inlet grooves 19 and the post-indentation grooves 20 are arranged in parallel at regular intervals in the left and right directions are divided into two rows before and after the housing 12, and in the front and rear directions. In order to prevent the front and rear indentation grooves 19 and 20 from facing each other, each of the front and rear two indentation grooves 19 and 20 is arranged in a zigzag shape in the plane direction of the housing 12 and also in the height direction (housing thickness direction). It is divided into two rows of the upper side and the lower side, and in the downward direction, it is disposed in a zigzag shape so that the front and rear indentation grooves 19 and 20 do not face each other.

The front and rear contacts 13 and 14 which will be described later are press-fitted to the front and rear press-in grooves 19 and 20 and are integrally assembled to the housing 12. Subsequently, as shown in FIG. 5, the slider 15 is slidably attached to the attachment port 17 of the housing 12, and the slider 15 is provided in a stand-by state where the flexible substrate 16 is attached.

In this case, since the contacts 13 and 14 in the front and rear two rows are distributed in a zigzag form not only in the plane direction but also in the height direction in the left and right directions of the housing 12, the contacts are three-dimensional zigzag arrangement in the housing. The distance between the contacts distributed in the vertical direction as well as in the front, rear, left, and right directions on the housing 12 can be increased. For this reason, even if the flexible board connector 11 is miniaturized, since the contact distance provided adjacent to it by securing an insulation distance does not interfere, it does not interfere, and the space | interval suitable for contact | exhaustion of a contact can be ensured. In particular, the thin part of the resin layer 12a (refer FIG. 4) between the contacts in a parallel direction can be eliminated, resin shortage is eliminated, and resin molding of the housing 12 becomes easy. For this reason, the metal mold | die parts used for shaping | molding of a housing | casing also lose | eliminate a thin part, and the metal mold | die rich in durability can be obtained. In addition, the resin layer 12a between the contacts can be secured to a certain thickness to eliminate the thinning, so that the thinning of the contact itself can be avoided, and the contact itself is terminated without losing the elasticity of the contact, thereby providing stable elastic contact force to the contact itself. The contact pressure with the flexible substrate 16 can be ensured, and the contact reliability with the flexible substrate 16 is improved.

In addition, since the contacts in the front and rear two rows are distributed in a zigzag form in the planar direction and in the height direction, the contacts having a sufficiently long elasticity in the front and rear direction of the housing can be disposed without facing the front and rear directions. Therefore, since the contact portion of the contact can be supported by one side support for a long time, the contact portion of the contact can have a long spring length. For this reason, stable contact performance can be made to a contact part.

The above-mentioned all contacts 13 are provided in a long J-shape, press-fitted into the voltage inlet groove 19 from the front side of the housing 12 in the state laid down in the longitudinal direction thereof, and as shown in FIG. The upper contact part 13a is formed in the J-shaped inner end part of this all contact 13, and this upper contact part 13a is interposed in the upper part in the cavity part 18. As shown in FIG. In addition, the outer end 13b of all the contacts 13 protrudes toward the front side than the front side of the housing 12.

After the above-described contact 14 is provided in a long co-shape, the co-shape is pressed in and attached to the post-indentation groove 20 from the rear side of the housing 12 in a state in which the co-shape is laid in the longitudinal direction, and is shown in FIG. 7. As described above, the upper contact portion 14a is formed on the upper inner end of the post-contact 14 at the U-shape, and the upper contact portion 14a is interposed above the cavity 18. In addition, the outer end 14b of the back contact 14 protrudes toward the rear side of the housing 12.

The outer ends 13b and 14b of these contacts protrude outward of the housing 12 and are electrically connected to a circuit on the substrate when the housing 12 is mounted on the control substrate. In addition, in order to press-fit and attach the contacts 13 and 14 in the front-rear direction of the housing 12, the outer end portions 13b and 14b of all the contacts are dispersed in a zigzag shape before and after the housing 12 and are taken out. For this reason, a connection space becomes enough in the wiring on a board | substrate.

Next, the slider 15 is formed of an insulating resin material and allows the slider 15 to slide inward toward the inside of the attachment opening 17 opened on the front surface of the housing 12, and prevents the locking portion 15a from falling off on both sides of the tip portion. A stepped pressing surface 15c (see FIG. 7) having a slide guide surface 15b (see FIG. 1) and which is in uniform pressure contact with the upper contact portions 13a and 14a of the contacts 13 and 14 on the upper surface of the center portion. Have Moreover, the press-in stopper part 15d is provided in both sides of a rear end part.

When the flexible board 16 is connected and fixed using the flexible board connector 11 configured as described above, as shown in FIGS. 8 and 9, the conductive tip of the flexible board 16 is attached to the housing 12. When the slider 15 is inserted inward from the sphere 17 into the inner cavity 18, and the slider 15 is slid forward at the same time as the insertion operation, the stepped pressing surface 15c on the upper surface of the slider pushes the conductive tip upward when moving forward. It is raised and electrically connected to the upper contact portions 13a and 14a of the contacts 13 and 14 facing the upper side thereof, and stable contact pressure can be maintained by the mechanical pressing force of the slider 15. .

In this case, since the upper contact portions 13a and 14a of the contacts are arranged on the upper surface side, an economical flexible substrate of a single-sided type which is brought into contact with the upper portion of the cavity 18 can be applied.

In addition, when the slider 15 is retracted as if it is pulled out toward the front side of the housing 12, the upward pressing force by the slider 15 is opened, and the conductive tip of the flexible substrate 16 is free and can be taken out. .

Second Embodiment

As shown in FIG. 10 and FIG. 11, the flexible board connector 101 of this 2nd Embodiment has the press-in direction of the back contact 104 compared with the flexible board connector 11 of 1st Embodiment. The type of press-fitting downward from the upper side of the housing 102 and the point of adjusting the height positions of the upper contact portions 103a and 104a of the front and rear contacts 103 and 104 to the same height are different. Although the shape of the slider 105 is different, it has the same function and the same operation and effect can be obtained, so only the differences will be described.

The upper press-fitting groove 106 of the housing 102 described above is provided in parallel in the left-right direction on the rear side of the upper surface of the housing 102, and the post-contact 104 is laid down in a long L-shape from the top. Press and attach at.

In this case, as shown in FIGS. 12 and 13, the upper contact portion 104a is provided at the inner end of the L-shape of the post contact 104, and the upper contact portion 104a is a cavity inside the housing 102. The part 108 is interposed from above and interposed above the cavity 108. In addition, the outer end 104b of the back contact 104 protrudes toward the rear side of the housing 102. In the figure, reference numeral 104c denotes a release preventing piece.

The outer ends 103b and 104b of these front and rear contacts protrude outward from the front and rear surfaces of the housing 102, and are electrically connected to a circuit on the substrate when the housing 102 is mounted on a control board. . In addition, when the contacts 103 and 104 are press-fitted from the front and the top of the housing 102 and attached to the positions before and after the housing 102, the contacts 103 and 104 in parallel in the left and right directions in the front and rear two rows are connected to the housing. In the plane direction of 102 and also in height direction, it arrange | positions and distributes in a zigzag form, respectively.

Also in this case, the contact attached to the housing is attached in a three-dimensional zigzag arrangement in which the contacts are arranged in a zigzag arrangement in each of the plane direction and the height direction, and the same effects as in the first embodiment can be obtained. In addition, since the back contact 104 can be press-fitted from the upper side of the housing 102, the press-fit operation can be carried out from the upper surface of the flat housing 102, and press-fitting suitable for attachment to the housing is possible. Become.

Specifically, when press-fitting a contact into a housing, the pressurization area of the part which presses the contact can be enlarged. Moreover, the advantage that the shape of the press fitting jig used at that time becomes simple can be acquired. In addition, since the long post contact 104 is press-fitted in the short side direction (height direction) of the housing 102, the press-in distance can be shortened and stable attachment can be achieved.

In addition, the upper contact portions 103a and 104a of the front and rear contacts 103 and 104 can be arranged upward, and the slider 105 pushes the conductive tip of the flexible substrate 107 upwards to face the upper side. The upper contact portions 103a and 104a of the contact can be easily contacted, and an economical flexible substrate of a single-sided type can be applied.

In addition, since the height positions of the upper contact portions 103a and 104a of the front and rear contacts 103 and 104 can be arranged so as to be arranged upward, the pressing direction of the slider 105 and the shape of the slider 105 are complicated. It is possible to share a simple push-up surface 105a having a flat shape suitable for fabrication, thereby simplifying the shape of the slider 105.

In this case, the slider 105 has a box shape in which the front and rear surfaces are open, and slides the bottom surface so as to be inserted into the front opening of the housing 102 so that the slider 105 is easy to handle because of the box shape. ), The end face of the slider 105 can be slid with a fingertip to perform a slide operation. In addition, since the upper surface of the slider 105 has a large flat surface, it is easy to apply this upper surface to the adsorption surface of the automatic machine for connector mounting, and it can contribute to the mounting on a board | substrate.

[Third Embodiment]

As shown to FIG. 14 and FIG. 15, the flexible board connector 141 of this 3rd Embodiment has the press-in direction of all the contacts 143 compared with the flexible board connector 11 of 1st Embodiment. Since the type of press-fitting from the lower side of the housing 142 to the upper side is different, and the shape of the housing 142 or the slider 145 is different, it has the same function and the same operation and effect can be obtained. do.

The lower surface press-fitting groove 146 of the housing 142 described above is provided in parallel to the front side of the lower surface of the housing 142 in a left-right direction, and in this state, all the contacts 143 provided in a long J-shape are laid down from below. Press in and attach.

In this case, as shown in FIGS. 16 and 17, the upper contact portion 143a is provided at the inner end of the J-shape of all the contacts 143, and the upper contact portion 143a is a cavity inside the housing 142. It is interposed above the part 148. In addition, the outer end portion 143b of all the contacts 143 protrudes toward the front side of the housing 142. In the figure, reference numeral 143c is a missing prevention piece.

In addition, the outer ends 143b and 144b of the front and rear contacts protrude outward from the front and rear surfaces of the housing 142, and when the housing 142 is mounted on the control board, it is electrically connected to a circuit on the board. . In addition, when the front and rear contacts 143 and 144 are press-fitted from the lower side and the rear of the housing 142 and attached to the positions before and after the housing 142, the contacts 143 and 144 which are parallel in the left and right directions in the front and rear two rows are In the planar direction of the housing 142, and also in the height direction, they are distributed and provided in a zigzag form, respectively.

Also in this case, the contact | attachment attached to a housing is attached by the three-dimensional zigzag arrangement which becomes a zigzag arrangement in each of a plane direction and a height direction, and the effect similar to 1st Embodiment can be acquired. In addition, since all the contacts 143 can be press-fitted from the bottom of the housing 142, the press-fit operation can be carried out from the lower surface of the flat housing 142 having a large area, and press-fitting suitable for attachment to the housing is possible. Become.

Also in this case, when pressing a contact into a housing, the pressurization area of the part which presses the contact can be enlarged. Moreover, the advantage that the shape of the press fitting jig used at that time becomes simple can be acquired. In addition, since the long post contact 144 is press-fitted in the short side direction of the housing 142, the press-in distance can be shortened and stable attachment can be achieved. In addition, since the long all-contact 143 is press-fitted in the short side direction of the housing 142, the press-in distance is shortened and stable attachment is possible.

In addition, since the upper contact portions 143a and 144a of the front and rear contacts 143 and 144 can be arranged upward, the conductive tip of the flexible substrate 147 is pushed upward by the slider 145. Only the upper contact portions 143a and 144a of the contact can be easily contacted with each other, and an economical flexible substrate of a single-sided type which contacts the upper surface can be applied.

Regarding the upper contact portion 143a of the above-mentioned all contacts 143, at the time when the flexible substrate 147 is inserted into the housing 142, the contact tip structure is sandwiched between the upper and lower surfaces of the conductive front end 143a. This improves the attachability of the flexible substrate 147.

In addition, as an example of the slider 145 used here, the rotation type thing is employ | adopted and the axial support part 145a formed in the lower part of this slider 145 is axially supported by the housing 142, and When the axial support part 145a is provided at a rotation point, and the flexible substrate 147 is inserted, the slider 145 is rotated so that the flexible substrate 147 and the upper contact portions 143a and 144a of each contact are rotated. It has a strong contact configuration.

As described above, since the contacts in the front and rear two rows are distributed in a zigzag form not only in the plane direction but also in the height direction in the left and right directions of the housing, the contacts are three-dimensional zigzag arrangement in the housing, so that the contacts are not only front, rear, left and right, but also up and down directions. Also, the distance between contacts can be increased.

As a result, even if the flexible board connector is downsized, it can be arrange | positioned at the space | interval which secured the appropriate insulation distance between contacts. In addition, a thin layer of the resin layer between the contacts can be avoided and a thickness suitable for manufacturing the housing can be ensured. For this reason, the mold part also loses a thin part and obtains a durable mold which is hard to be damaged. In addition, it is easy to manufacture, thereby further facilitating downsizing of the housing. In addition, since the thinning of the contact can be avoided, the contact is terminated without losing the elasticity of the contact itself, and the contact pressure with the flexible substrate can be ensured with a stable elastic contact force, and the contact reliability with the flexible substrate is improved.

In addition, in order to increase the insulation distance not only in the front, rear, left, and right directions, but also in the vertical direction between the contacts, shortage of resin filling between the contacts can be avoided, whereby a stable molded article can be obtained. In addition, since the front and rear two rows of contacts are arranged in a zigzag shape in both the planar direction and the height direction and do not face each other in the front and rear direction, the spring length in the contact length direction extending in the front and rear direction of the housing can be lengthened. For this reason, each contact can be made to have stable contact performance.

In correspondence between the configuration of the present invention and the configuration of the above-described embodiment,

Although the pressing member of this invention corresponds to embodiment slider, this invention can be applied based on the technical idea shown in a claim, and is not limited only to the structure of embodiment mentioned above.

For example, in the above-described embodiment, the contact portion of the contact is arranged and set up on the upper side, but the present invention is not limited thereto, and the contact portion may be arranged on the lower side, and in this case, the same operation effect can be obtained only by changing the direction of the contact portion. have.

According to this invention, since the distance between contacts can be extended and arrange | positioned, even if the flexible board | substrate connector is miniaturized, it can arrange | position at the interval which secured the appropriate insulation distance between contacts. In addition, a thin layer of the resin layer between the contacts can be avoided and a thickness suitable for manufacturing the housing can be ensured. For this reason, a mold part also loses a thin part and can obtain the durable die which is hard to be damaged, and also manufacture becomes easy and it can promote downsizing. In addition, since the thinning of the contact can be avoided, the contact is terminated without losing the elasticity of the contact itself, and the contact pressure with the flexible substrate can be ensured with a stable elastic contact force, and the contact reliability with the flexible substrate is improved.
